This week I'm reading The Sorrows of Young Werther by Johann Wolfgang von Goethe. More accurately, I'm rereading it, I had to read it for literature classes but that seems to be have been ages ago and I don't remember much about it except that it definitely struck a nerve with me at that time unlike other books that we were assigned to read. 

On its publication in 1774, The Sorrows of Young Werther gained an instant cult following. European readers were captivated by the rapturous ruminations of Werther, Goethe's typically Romantic protagonist whose extreme passion leads to self-destruction. Public fascination gave rise to a fanatical copycat culture, in which men dressed in Werther's signature outfit, women wore "Eau de Werther", and at least one person committed suicide with a copy of Young Werther in her pocket. The sensational novella united people in self-obsession and a desire for a sublime sense of individuality.
